Joe Corona and Greg Garza played a hand in an upset win, as the Xolos knocked off reigning FIFA Club World Cup champion Corinthians in a Copa Libertadores group stage showdown Tuesday.

Corona drew the start on the left side of Club Tijuana's midfield and watched his team twice nearly fall behind in the first half, but both Corinthians goals were called back for offside.

In the 64th minute, Corona drew the free kick that led to the game's lone tally. Fernando Arce stepped up and played a long, looping ball into the box that was knocked around and ultimately back-heeled home by Javier Gandolfi. Garza entered in the 85th minute to help Club Tijuana secure the shutout.

It was Corona's third consecutive start in Copa Libertadores play, while Garza made his first appearance. Fellow American Edgar Castillo missed the game after undergoing surgery Monday to repair facial fractures suffered in Club Tijuana's weekend loss to Atlas.

With the win, the Xolos move to 3-0 halfway through play in Group 5, five points clear of the Brazilian giants who sit in second.

Corinthians will look to exact revenge next Tuesday when Corona, Garza and Co. visit São Paulo to continue group play.
